Road Construction Chemicals
Product Position:
SBS (Styrene-Butadiene-Styrene block copolymer) asphalt modifier is the most widely used road asphalt modifier globally. This product features star or linear SBS pellets/powder, which is incorporated into base asphalt through physical swelling and shear dispersion, forming a 3D network structure that comprehensively enhances high/low temperature performance, elastic recovery and fatigue resistance. Compliant with JTG F40 and GB/T 45464-2025.
